This is the unit that had me know I made a good decision in choosing to study software engineering. I found the assignments in this unit challenging but thoroughly enjoyable. This unit can be seen as a continuation from COMP1010, further exploring search and sort algorithms, linked lists versus array lists, stacks and queues, tree-based data structures and traversals, hashing, and a light introduction to time complexity. (Note: I did this unit as COMP225 in 2017 S1. StudentVIP doesn't let me select this.)
